Table 28: Fan Tray LED
Color LED Status
Amber Off
On Steadily
NOTE: The fan tray LED provides additional safety measures. Even though
you can remove the fan tray while the fans are still running, we strongly
recommend that you wait until the fan tray LED lights steadily amber
(indicating that the fans are not running) before you remove the fan tray.
NOTE: The fan tray supports hot-swappable functionality. We recommend
you to reinstall the fan tray within three minutes; otherwise, the services
gateway temperature may exceed the maximum recommended room
temperature and the device shuts down automatically in four minutes.
